<p>A vehicle bumper support comprising two tubular telescopic assemblies, each including a transverse wall having an aperture therethrough, a first elastic tubular member within one of said assemblies at one side of the transverse wall thereof having one end sealed about the aperture through the wall and the other end closed. A second elastic tubular member more elastic than the first tubular member within the other of said assemblies and at the opposite side of the transverse wall of said one assembly. The second elastic member has one end sealed about the aperture through the transverse wall of said one assembly and its opposite end connected to the transverse wall of said other assembly and closed. The chambers formed at least in part by the elastic tubular members are filled with liquid flowable from one chamber to the other through the aforesaid aperture in the transverse wall of said one assembly as restricted by a rod-like member connected to the transverse wall of said other assembly and extending into said aperture. The rod-like member is of decreasing diameter in the direction of the transverse wall of said one assembly and varies the resistance to the flow of liquid from one chamber to the other. A ring-like flexible member exteriorly of said second flexible tubular member tapering outwardly and toward the transverse wall of said other assembly at the side of the transverse wall of said one assembly facing the transverse wall of said other assembly.</p> |
